VIOLIN.

Specification of Letters Patent.

Patented May 12, 1914.

Application and April 1, 1912. Serial No. 687,887.

: is made more mellow by an easily effected treatment of the surfaces of the bridge and body. My experiments have been long and careful with 'three excellent violins, but I have confined my efforts mainly to the common grade of instrument.

'The improvement'can be applied to old violins but it may be preferable to apply it: at the time of the, original manufacture. It consists in a thin tight-fitting coat of requisitely rigid pile material glued on the bridge or other sound-giving surface of the wood and terminating closely at the edge of the supporting part.

The following is a description of what I consider the best means of carrying out the invention in a small way.

The accompanying drawings form a part of this specification.

Figure 1. is a. face view of a bridge before bein treated. Fig. 2 is a cross section on the line 2-2 of the same bridge in the same ordinary stage. Fig. 3 is a corresponding section after the covering has been applied but has not been trimmed. And Fig. 4 is a similar view after the treatment is completed by the specially close removal of the surplus. And Fig. 5 is a perspective view of a violin having the coating applied according to my'invention to the bridge and presenting in all respects the ordinary neat appearance.

Similar letters of reference indicate like parts in all the figures where they appear.

glue having the property of being hard when dry and while the glue is soft the coat.-

ing thus prepared is pressed on each face I of the bridge.

The bridge is coated on both sides but the top edge where the strings pass is left bare, and the lower edge that rests on the belly of the violin is also left bare. velure is made a little larger than the bridge and when the glue is thoroughly dry, the overhang is trimmed off with shears. Theholes are burned out with a hot iron and the slots by a hot knife, leaving the ma terial specially clean, the slight presence of charcoal for a little time being of no consequence.

The entire back of the violin is similarly coated on the outside with velure or other soft material similarly fastened to the wood with glue and similarly trimmed to remove the surplus.

The glue I have used successfully is the we1l-known Le Pages, a glue which can be applied cold. I out the velure into pieces each a little larger than-the wood to which it is to be applied. I apply the liquid glue liberally with an ordinary brush to the wood and bring the fabric in the ordinary dry condition into contact in the right position, and press it home with the hands. Letting it dry in the shade a few hours it is ready for the trimming.

The overhang is removed without straining the adjacent particles so as to disturb the union of the remainder with the wood. I have used shears for the large border about the back and a hot iron of small size for burning around the edges of the bridge and especially for disposing of the surplus around the recesses a and around the hole a.

The finishing may be in all respects the The piece of I claim as my invention- 1. A VlOllIl bridge covered with fibrous material terminating closely at the edge of the supporting part and provided with a filling of varnish.

2. A violin bridge covered on both surfaces with a fibrous material provided with a filling of varnish.

'3. A violin bridge partially covered with a pile fabric glued by its flossy side and terminating closely at the edge of the supporting part.

4-. A violin bridge covered with pile fabric glued by its flossy side terminating at the edge of the supporting part as herein specified.

5. A violin bridge covered with pile-fabric glued by its fiossy side terminating at the edge of the supporting part as herein specified and provided with a filling of var nish.

6. A violin bridge'covered with a pile fabrio provided With a filling of varnish in combination with a violin body having its back covered with a. simlar imaterial both affixed by gluing and having the fibrous material terminating closely at the edges of the supporting part.
